Geocache Description:

This earthcache has been placed along the Gary Junction Road as a part of a series of caches which aim to give the traveller a better understanding of the geology in this remote region.


Haasts Bluff, near the Aboriginal community of the Ikuntji and which is commonly known also by same name Haasts Bluff is approximately 230 km west of Alice Springs in Northern Territory Central Australia.  It is located within the MacDonnell Ranges.

The Haasts Bluff community takes its name from this outcrop, which was given this name in 1872 by the explorer Ernest Giles, after the New Zealand geologist, Julius von Haast.

The bluff is composed of Muscovite-biotite-quartz schist interlayered with quartz-muscovite metapsammite, with varying degrees of tourmalinisation; rare quartzite and garnet-bearing schist.  The same geology is found throughout the Haasts Bluff Domain.  Perhaps interested visitors might look for garnets....

To log this cache, go to the listed coordinates and email me the answers to these questions.  You can immediately log the find and if there are any problems I will contact you.
